I accidentally put thermal paste inside the socket. I considered adding some alcohol to clean it up, but after about three hours everything seemed dry. The PC wouldn’t start, fans were still spinning, but it didn’t boot. Now I’m worried if I had to replace the socket and CPU.
Determine if the component uses an AMD socket or Intel platform. The current setup suggests a 70% IPA with 30% water, pointing toward an Intel-based design. To prepare the board, align it flat on a socket and let it rest undisturbed for a few days while drying.
What CPU and board are you using? PGA boards (AM4) can be tricky to clean because tiny paste particles might remain in the socket. Using isopropyl alcohol is safe as long as it dries completely before powering up. For cleaning the CPU, soak it in a cup of alcohol for a while, brush off any residue with a toothbrush, then let it air dry on paper towels. I’ve had similar issues before—after doing that, everything worked fine again. I also bent some pins on a 3900X by accident, but managed to fix them. I usually use mostly isopropyl, keeping the solution less watery.
So, yeah, get yourself a little bit of 91% (or higher, the higher the better) in a syringe and gently squirt tiny amounts onto the socket. Then flip the board over, put it socket-down in a safe place and walk away for several days while it all dries. Should be fine after that unless something shorted.
It's okay to power on the motherboard along with the CPU inside.
They used a syringe because it worked fine before switching to a spray bottle. It wasn’t as effective with IPA unless you kept things well-maintained. A regular shotring would disappear once the moisture evaporates. If it still won’t turn on after two days, remove the heatsinks and CMOS battery, clear the CMOS, then run the short power button for two minutes. Rinse, then soak in water without detergent (test yourself first) for an hour or two, then let it dry for a day or two based on the weather. After removing it from the water bucket, shake the board thoroughly to reduce water and speed up drying.
It waited for roughly seven hours before it functioned properly, which is unexpected but I’m relieved. I’m just glad it worked now.
